The moral is simple: keep your mouth shut, especially when you're working during the wartime in a factory, which produces racing cars only, or someone can (or even must) get murdered. Not a good movie, not a bad either. The ending is abrupt and artificial, which seems to be a common plague of Third Reich's crime movies. Gustav Fröhlich could never get rid of his silent era mannerisms and overacting. But on the other side, this film is not boring and has to offer some decent plot turns and acting.

A taxi driver, (Piel), finds an odd contraption on the back seat that renders him invisible, but his friend steals the device to rob a bank. An inventive comedy.

In this early version the classic "Hound of the Baskervilles" mystery is not faithfully adapted, Watson's character is absent and there are two Holmes. Holmes' foe is called Stapleton and he menaces Holmes' client Lord Henry and his fiancée, Laura Lyons, masquerading himself as Holmes. Hidden passages, hand bombs and mechanical devices abound, reminding more of a serial than of a Conan Doyle story.

German colonial soldiers fight against the British during World War I.

Blonde goddess Marika Rökk plays Julia Koster, a ravishing red-headed musical revue star and her opening number, "At Night It Isn't Right To Be Alone", playing to a packed theater, is both an eye-popper and a jaw-dropper.
